摘　　要：为了设计消色差性能优良的三元复合λ/4波片,根据复合波片原理,利用蚁群算法对三元复合波片进行了优化设计,即通过改变三波片的厚度和精确调整复合角,使消色差范围拓宽到500nm,相位延迟偏差在0.81%左右。这种优化设计对于拓宽消色差范围,提高延迟精度具有实用价值。According to the composite wave - plate theory, I use ant colony algorithm to calculate composite Angle and three wave plate thickness then through matlab do simulation experiment and analysis the error . experimental result shows that the retardation deviation of this device is within 0.81% covering file spectrum scope of 500nm. 33ais paper supplies considerable theoretical premise to the design of composite achromatic wave - plate, and provides theoretical basis for wider achromatic spectral range and higher precision. So our work has very important pratical reference value, in order to design some high - quality infrared composite aciuomatic wave - plates.
